KOBY KOHN, 0F LINCOLN, NEBRASKA, ASSIGNOR T0 WESTERN FURNITURE AND MANUFACTURING COMPANY, OF NEBRASKA.

To all whom it may concern:

Be it known that I, KOBY KoHN, a citizen of the United States, and resident of Lincoln, county of Lancaster, State of Nebraska, have invented certain new and useful Improvements in Mattresses, of which the following is a specification.

The present invention relates to improvements in mattresses and has for its object to provide a mattress which will retain its shape and elasticity or softness to a greater extent than is possible with the constructions heretofore employed.

It is well known that practically all mattresses tend to sink in or be undesirably compressed at the portion or section which is subjected to the greatest weight when in use and such compression frequently results in spreading the mattress in the direction of its width beyond the confines of the bed or supporting frame and also destroys the desired uniform level of the upper surface. It has been proposed to increase the amount of material in that portion of a mattress that is required to support the greatest weight when in use but this, according to the methods heretofore employed, has

rendered the mattress undesirably hard if suflicient material is employed to prevent sagging.

The present invention is particularly designed to avoid these objections and, while it is not limited to felt mattresses, has been found to be particularly adapted for use with that type or form of mattress; and such an embodiment of the invention is illustrated in the accompanying drawings.

Referring to the drawings, Figure 1 is a perspective view of the upper layer of a felt mattress. Fig. 2 is a similar view of the bottom layer. Fig. 3 is a similar view of the intermediate reinforcing section. Fig. 4 is a view showing the manner in which the several sections are assembled, the filling machine being illustratedmore or less conventionally. Fig. 5 is a view similar to Fig. 4, showing the several layers fully compressed. Fig. 6 is a perspective view of a complete mattress, part of the outer casing or cover being cut away to expose the filling section. Figs. 7 and 8 illustrate a modified Specification of Letters Patent.

form of the reinforcing section. Fig. 9 is an end view of a reinforcing section made In the manner illustrated in Figs. 7 and '8 and additionally folded to cause its original ends to abut.

A mattress constructed in accordance with the present invention comprises a body form of a bottom layer A, an upper layer B and an intermediate layer C, the latter being folded or rolled upon itself, and positioned between the layers A, B, at that section of a mattress which receives the greatest weight when in use. Preferably the in termediate layer C extends continuously from side to side of the mattress but is shorter than either the top or bottom layers, B, A. Referring to Fig. 3, it will be seen that the body of the intermediate layer is so folded or rolled upon itself that the ends C, C thereof are rounded so that they are not preceptible in the finished mattress. In this embodiment of the invention the ends of the body, after being folded or rolled, abut as indicated at G I The several layers referred to are assembled in a suitable machine known as a filler, which is conventionally illustrated in Figs. 4 and 5. As shown this machine comprises a suitable base D, a tubular support D for the mouth of the cover or casing E, a pushing member D by which thecompressed layers can be forced through the guide D into the casing E and a compressor bar or plate D When the several layers are first placed in the machine they will occupy approximately the relative positions shown in Fig. 4. y depressing the compressor plate or bar D the body will be caused to assume the form shown in Fig. 5, in which it will be seen that the parts of the top and bottom layers, between which the folded reinforcing layer C is arranged, will be compressed to a greater extent than the portions beyond the ends of said intermediate layer. The complete body will have a uniform thickness throughout and when the same is forced into the coveringor-casing E the flap E at the originally open end thereof is secured in place and the body and covering connected by tufting, as shown, or any other suitable means. The form of mattresses including an embodiment of the invention that is illustrated is provided about both its top and bottom edges with an enlargement, or has what is known to the trade as a roll or imperial edge.

It will be understood that the proportions of the different layers will be varied according to the weight which it is desired that the finished mattress shall have. The intermediate layer C formed and arranged as described secures the desired reinforcement of the mattress without undesirably increasing the weight thereof or making the reinforced section hard and unyielding.

Experience has shown that if a body of the so-called felt, which is commonly made of cotton, is folded or rolled as herein shown it is adapted to resist compression or distortion to a considerably greater extent than an unfolded or unrolled layer of thesame material. This is believed to be due to the fact that by the folding or rolling operation the fibers of each layer or section thereof are arranged in different superposed planes, the sections of each original layer being connected at the ends by portions that extend transversely of the direction of the' fibers in the main body. As shown in Figs. 1 to 6 the top and bottom layers and the reinforcement referred to, before the latter is each composed of a series of superimposed evident that closely adhering layers; but it will be evident that said members A, B and C may each originally consist .of what is known as a one bat felt. Such a construction of the reinforcement, C, is shown in Figs.

and 8. That is, instead of making the reinforcement in the manner described and shown in Figs. 3 to 6 by folding or rolling a body comprising a series of superposed layers with its ends abutting, said member, 0*, may be formed of a single continuous piece folded or rolled up, as shown in Fig. T and then compressed to the form'shown in BAigBS before it is placed between the layers The reinforcement C formed from a single bat, as illustrated in Figs. 7 and 8, may be further folded upon itself to cause its ends to abut, as shown in Fig. 9.

While the embodiment of the invention illustrated is a one-piece mattress in which the reinforcing layer C is approximately equally distant from both ends, it will be this is not essential. For example, in a two-piece mattress the reinforcing section would be arranged nearer one end of the larger section than the other. The reinforcing section is, as before described, arranged at that section of the mattress which is subjected to the greatest weight when in use.

- pressed to a greater extent between folded or rolled, are

- tress and initially of The complete mattress constructed according to the present invention will be of uniform thickness and the elasticity and softness thereof will be equal to that of mattresses as ordinarily constructed in which the filling material is distributed practically uniformly throughout the casing. It will be seen that with the present invention the top and bottom layers will be comthe ends of the intermediate layer than beyond such ends and the fibers of. the several layers will be so engaged as to form a substantially single body which is of greater density at that portion on which the greatest weight is applied when the mattress is in use than at other portions. 7

While the previous description refers to one form of means for introducing a mattress body constructed in accordance with the present invention into a covering or casing, it will be evident that other means for introducing the filling into such a casing can be employed.

Having described the invention what is claimed is:

1. A mattress .which is of greater density in the section thereof that receives the great est weight when in use than at points between opposite ends of the mattress and said section, said intermediate section including a reinforcement formed by a body of mattress filling material that is upon itself.

2. A mattress, which is of greater density in the section thereof that receives the greatest weight when in use than at points between opposite ends of the mattress and said section, comprising upper and lower layers, both extending continuously throughout the surface area of the mattress, a body of suitable mattress filling material folded or rolled upon itself and arranged between said layers in the section of the mattress that is subjected to the greatest'weight when the mattress is in use, and a cover inclosing all of said parts.

3. A felt mattress comprising upper-and lower layers each extending continuously throughout the length and width ofthe matthe same thickness at all points, a shorter layer, formed by a body folded or rolled upon itself, arranged between the portions of the upper and lower layers that are subjected to. the greatest weight when the mattress is in use, and a cover inclosing all of said parts, the said outer layers being compressed extent between the cover and-intermediate layer than at other points 4. A mattress which is of greater density in the section thereof that receives the greatest weight when in use than at points to a greater folded or rolled v between opposite ends of the mattress and In testimony whereof I aflix my signasaid section, said lntermediate section inture in presence of two Witnesses.
